The USPTO charges fees at every step of the patent process and these fees are the only fixed cost in the process. The USPTO charges a required $330 to file an application, $540 for a search, $220 for an examination, $1,510 to issue the patent if it passes the examination, plus $7,750 in maintenance fees over the 20 years that the patent is in force. Hence, the total to file and go through the process is $1,090, but the total to receive the patent and keep it in force is $10,350. Note that independent inventors and small businesses receive a 50 percent discount on fees but that the USPTO charges more for extra or late paperwork.Is my idea already patented?
Most inventors dont really want to find their invention in someone elses patent, so the spend 5 minutes looking and then declare that they can't find it. It takes longer than that. If your invention is a mouse trap, you might find it by searching for those words...but the killer patent might instead describe a rodent restriction device or an automatic small animal containment system. Look for it like you want to find it. Talk to a registered patent attorney for immediate advice on protecting your idea (in the form of a provisional patent) while you determine if it is worth pursuing, in view of a preliminary search of related inventions, patented or not. Even if you don't find any "patents" showing your idea used in an invention, it could still be unpatentable because someone else used it or described it before you filed your provisional application.Utility patents
Utility patents are for either a: process, machine, article of manufacture, composition of matter or an improvement of any of the above. Patent protection is also available for (1) ornamental design of an article of manufacture (design patent) or (2) asexually reproduced plant varieties by design and plant patents (plant patent).Do a Patent Search
Would you like to see a real patent ? You can! Finding patents is almost like being a detective. A patent search is something that all inventors have to do before they can patent their invention. It lets inventors find out if anyone else has ever invented the same invention. Another benefit is that conducting a patent search is also a great way to find out about the history of old inventions.How difficult is a patent search?
Conducting a thorough patent search is difficult, particularly for the novice. Patent searching is a learned skill. A novice in the United States could contact the nearest Patent and Trademark Depository Library (PTDL) and seek out search experts to help in setting up a search strategy. If you are in the Washington, D.C. area, the USPTO provides public access to collections of patents, trademarks, and other documents at its Search Facilities located in Arlington, Virginia. It is possible, however difficult, for you to conduct your own patent search.
